    <p>I want to send this CSV data to SOLR.</p> <pre><code>id,author,name,year,category 001-001,H. G. Wells,The Time Machine,1895,Fiction 001-002,H. G. Wells,The Wonderful Visit,1895,Fiction </code></pre> <p>Here is my code which doesn't work.</p> <pre><code> private static final String postURL = "http://localhost:8983/solr/update/csv?separator=,&amp;commit=true"; public static void main(String[] args) throws IOException { BookCsvIndexer poster = new BookCsvIndexer(); BufferedReader dbr = new BufferedReader(new FileReader("E:/solr-example/csv/books.csv")); String line; StringBuilder dsb = new StringBuilder(); while ((line = dbr.readLine()) != null) { dsb.append(line); } dbr.close(); String data = dsb.toString(); System.out.println(data); poster.doPost(data); } public void doPost(String data) { String contentLength = Integer.toString(data.getBytes().length); System.out.println("Length=" + contentLength); StringBuilder sb = new StringBuilder(); try { URL url = new URL(postURL); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); connection.setRequestMethod("POST"); connection.setRequestProperty("Accept", "text/plain"); connection.setRequestProperty("Connection", "close"); connection.setRequestProperty("Content-Type", "application/csv; charset=utf-8"); connection.setRequestProperty("Content-Length", "" + contentLength); connection.connect(); if (data.length() &gt; 0) { OutputStreamWriter wr = new OutputStreamWriter(connection.getOutputStream()); wr.write(data); wr.flush(); wr.close(); } BufferedReader br = new BufferedReader(new InputStreamReader((connection.getInputStream()))); String output; System.out.println("Server Respose CODE=" + connection.getResponseCode()); while ((output = br.readLine()) != null) { sb.append(output); } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } System.out.println(sb.toString()); } </code></pre> <p>I can use this same code for sending JSON and other text files successfully by simply changing the 'Content-Type'. I have been using this same code for hitting many REST services. I can't understand why this code is not working for sending CSV to SOLR.</p> <p>Here is the SOLR log after running the above code.</p> <pre><code>INFO - 2013-11-21 11:20:09.090; org.apache.solr.update.DirectUpdateHandler2; start commit{,optimize=false,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false} INFO - 2013-11-21 11:20:09.093; org.apache.solr.core.SolrDeletionPolicy; SolrDeletionPolicy.onInit: commits: num=1 commit{dir=NRTCachingDirectory(org.apache.lucene.store.SimpleFSDirectory@E:\solr-example\solr\collection1\data\index lockFactory=org.apache.lucene.store.NativeFSLockFactory@15b46ef; maxCacheMB=48.0 maxMergeSizeMB=4.0),segFN=segments_1,generation=1} INFO - 2013-11-21 11:20:09.093; org.apache.solr.core.SolrDeletionPolicy; newest commit generation = 1 INFO - 2013-11-21 11:20:09.094; org.apache.solr.update.DirectUpdateHandler2; No uncommitted changes.

Now, I want to do the same using Java.</p> <p>Am I missing something?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
